One way to initiate multiple commands and logging from the receiver is to create DOS boot-up command files relating to specific functions. This will save time when you want to duplicate test situations and minimize set-up time. Any convenient text editor can be used to create command text files. The following example shows how a text file can be used to create a boot-file on a PC, and send it to the OEM4/OEMV receiver through DOS. It is assumed that the PCs serial port COM1 is connected to the receivers COM1 port, and that a remote terminal is connected to the receivers COM2 port. 1. Open a text editor on the PC and type in the command strings to be sent to the receiver upon start up. For example: com com2 115200 n 8 1 n off off log com2 bestposa ontime 1 log com2 rangea ontime 1 log com2 rxstatusa onchanged log com2 rxconfiga once 2. Save this with a convenient file name (for example, C:\GPS\BOOT1.TXT) and exit the text editor. 3. Use the DOS copy command to direct the contents of the BOOT1.TXT file to the PCs COM1 port: C:\GPS>copy boot1.txt com1 1 file(s) copied C:\GPS> 4. The receiver is now initialized with the contents of the BOOT1.TXT command file, and logging is directed from the receivers COM2 port to the remote terminal. Note: - Please ensure you have used a carriage return (hit the enter key) after typing the last line. - If you wish these to become part of the permanent configuration of the card, rather than just using them on boot-up, enter the SAVECONFIG command as the last line. - We recommend transferring multiple commands at low connection baud rate like 9600bps. (Transfer multiple commands at high baud rate might cause a race condition at times) - Please use the RXCONFIG log to double check all transferred commands got accepted by the receiver after the transfer.
